Emacs makes it very easy to split your workspace into panes of arbitrary size and shape. But out of the box it doesn’t make navigating the panes with only the keyboard very convenient. In this quick screencast I enable “windmove”, which makes it possible to switch focus to different panes using the arrow keys.

EDIT: Enabling org-replace-disputed-keys fixed the issue I ran into trying to use windmove keys in an org-mode file.
